Applying electronic technology to automobiles, using computers to replace human brains to accurately judge vehicle and road
conditions, and using electronic control systems to replace heavy mechanical control components are
important goals for the development of modern automobiles. The rapid development of electronic technology has greatly improved the various performances of automobiles. Modern
automobiles are no longer simply a means of transportation, but are developing towards easier driving and comfortable
space. The technology involved in this aspect includes the vision, convenience, comfort
and entertainment of automobiles, which are inseparable from the electronic control technology of the vehicle body and are
the development direction of automobiles today and in the future.
　　The HS-E2003 ECU, an automobile body electronic control unit developed by Shenzhen Hangsheng Electronics Co., Ltd.
, is characterized by the use of code-hopping remote control technology, communication interface
control technology between single-chip microcomputers, sensor technology, and functional modular integration technology to ensure the smooth implementation of all body control functions
, greatly improving the comfort, convenience and safety of the entire vehicle.
The basic principle of HS-E2003 is to use the single-chip microcomputer to realize related control according to the signals input by various switches and sensors
, such as front and rear wipers, lighting, front and rear washers, electric
rearview mirrors , remote control central door locks, electric windows and various buzzer alarm reminders. The whole
system includes eight control modules: front control unit, electronic clock alarm control unit (ETACS),
steering column control unit, window master control and key module, driver's seat window control module,
assistant seat window control module, rear left and right window control module. The system block diagram is shown in Figure 1.
　　The whole system adopts a microcomputer controller bus structure, which has a compact structure, reliable performance, and is easy
to realize various functional expansions. Traditional car body control uses independent components and discrete
components. The more functions are added, the more complex the car body wiring harness is, and the more difficult it is to assemble, which
greatly reduces reliability. HS-E2003 adopts modular
design for the control of the car body part. Many functions are integrated in one module. Only one communication
line is needed to connect the modules. The connectors between the body wiring harness are greatly reduced, and the safety and reliability are greatly improved. And
the function design is humanized. Most functions can be pre-set to have/not have their functions through specific
operation procedures without adding any cost.
　　Compared with the existing technology and process in the field of automobile body electronic control integrated system, this product
has the following advantages: 1. All the control parts of each module adopt 8-bit microcomputer chips, which have low power consumption and
strong anti-interference. The communication between modules is simple and only one communication data line is needed. Each module
can work in coordination or independently, and become a separate product, which is easy to install. This greatly
simplifies the automobile wiring harness, improves the reliability of the whole vehicle, and facilitates debugging and maintenance. 2. Remote control function, using
code jumping technology. The remote control sends a set of passwords, the host receives the passwords, decodes it and
checks and verifies it. After the verification is correct, the machine executes the door unlocking function, and the door can be opened and entered.
And the windows can be opened and closed by remote control outside the car. 3. Various warning buzzer functions, various functions in the car
are more humanized, making driving a car no longer a chore, and bringing great
comfort and safety to driving. 4. Various input status and fault self-diagnosis functions. Diagnostic instruments can be used to
detect whether each module and switch is working properly, providing a reliable basis for rapid fault diagnosis and
can replace imported products.
